The paranasal sinuses are hollow, airfilled spaces located within certain bones of the skull (Figure 627) All of the sinuses communicate with the nasal cavity (paranasal = "next to nasal cavity") and are lined with nasal mucosa They serve to reduce bone mass and thus lighten the skull, and they also add resonance to the voice This second feature is most obvious when you have a cold orSinus and nasal cancer occurs in the mucusproducing tissues that line the nasal cavity (the space behind the nose through which air passes to the throat) and the paranasal sinuses (hollow areas in the facial bones near the nose) More than half of nasal cavity and paranasal sinus cancers occur in the maxillary sinuses (hollow spaces on either side of the nose and below theAim The aim of this study is to measure the right and left maxillary and frontal air sinus dimensions and their application in age determination and gender identification Materials and Methods Twenty Posteroanterior (PA) skull radiographs were used for the study The width, length and distance across the right and left sinuses were measured using the Planmeca Romexis Viewer software

The sinuses are an airfilled cavity in a dense portion of a skull bone They actually decrease the weight of the skull The sinuses are formed in four rightleft pairs The frontal sinuses are positioned behind the forehead, while the maxillary sinuses are behind the cheeks The sphenoid and ethmoid sinuses are deeper in the skull behind the eyes and maxillary sinuses The sinuses · Sinuses of the face are cavities or spaces within the bones that help humidify the air and secrete mucus to help with air filtration Additionally, they contribute to the strength of the skull and its ability to resist traumaThe sinus cavities also allow more resonance to be added to the voice The sinuses are often referred to as the paranasal sinuses because of their location andTraumatic pneumocephalus in the context of trauma, sphenoid or skull base fracture needs to be excluded

 · Subtracting the volumes of the bony skull, air sinuses, and endocast from total head volume gives the volume of the remaining soft tissue To convert volumes to masses, volume (cm 3) was multiplied by density (g/cm 3) Ignoring the thin sinus epithelium, air sinus density was taken as zero, as was the resulting mass Density of the cranial endocast was assigned the density ofParanasal sinuses are a group of four paired airfilled spaces that surround the nasal cavity The maxillary sinuses are located under the eyes; · Sinuses are airfilled sacs (empty spaces) on either side of the nasal cavity that filter and clean the air breathed through the nose and lighten the bones of the skull

Frontal sinus, sphenoidal sinus,;Air Sinuses of the Skull Several of the bones of the skull have developed air spaces that are lined with mucous membrane It is this mucous membrane that becomes infected in sever cases of sinusitis It is also irritation of the mucous membrane that results in excessive fluid production that can fill the air spaces and give you a stuffed nose feeling Since these sinuses are embedded in0513 · There are two frontal sinuses located within the frontal bone of the skull They are the most superior of the paranasal sinuses, and are triangular in shape Drainage is via the frontonasal duct It opens out at the hiatus semilunaris, within the middle meatus of the nasal cavity

The bones of the face and skull near the nose contain four pairs of airfilled pockets, which are called the paranasal sinuses The paranasal sinuses include the following types of sinuses A maxillary sinus in each cheek Between six and 12 ethmoid sinuses on each side ofVentrally along the cetacean skull, connect the pharynx and middle ear cavities Mysticetes (baleen whales) have a large midline laryngeal sac Although cetacean air sacs do not appear to be homologous to paranasal sinuses, they may serve some analogous respiratory, vocal, or structural functions For example, these sacs may participate in gas exchange, thermoregulation,Air within cerebral venous sinuses need not always be due to septic thrombosis, skull fractures, nose blowing, rhinosinusitis, or barotrauma It can be iatrogenic through an intravenous access while intravenous medication or fluid is being injected Our case emphasizes the relevance of removing air bubbles completely and judiciously before starting an intravenous access
